Application led December 19, 1908. Serial No. 468,306.

To all .whom it may concern: j

Bc it known that I, EDGAR B. SYMoNs, residing at Milwaukee, inthe countyof `Milwaukee and State of Wisconsin, have invented a certain new anduseful Crushing-Machine, of which the following is a specification.

My invention relates to improvements in crushing machines' in which thecrushing members rotate,`and are given in their rotation a mutually"reciprocative movement, thereby operating to crush stone or othermaterial fed into the cavity between them.

The objects of my invention are, first, so.to improve t-he form of theopposing, crushing members so as to afford to material, during itstravel from the mouth to the exit of the crushing cavity,- alcontinually increasing crushing area, thereby' allowing the material tospread during the process of its reduction; second, to provide for theutilization of centrifugal force in maintaining afeeding pressurewhichshall vary with the speed and working capacitybf the machine; third, toprovide for changing the length of the crushing stroke, or reciprocativemovement of the opposing crushing members, as maybe necessary ordesirable to suit the various requirements or conditions of Work;fourth, to improve the method of taking up the wear of the crushingmembers, and also of adjusting their position relative to each other inorder to change the size of the product; and fifth, to produce acomparatively" light, strong, durable and easily reparable crushingmachine,- one especially efficient in `the production of sand, or in thereduction of stone or like material to .small particles.

Other minor objects appear in the description which follows.l

My invention consists of the rotative reciprocative crushing plates ormembers which form a cavity between them.

It-consists also in the means employed for supporting and rotating saidplates; in the" manner ofV determining and maintaining the angleof theirrespective planes of rotation; in the centrally located feeding orificein association with the outwardly converging Acrushing cavity andperipheral exit; and

also in the combinations of parts for effecting theobjects desired as.hereinafter specified and'definitely pointed out in the claims.

" In the following description reference is had to the accompanyingdrawings in which Figure 1 is a sectional plan of. my ma* chine with thefeeding spout removed, and taken 'on the line M N of Fig. 2. Fig. 2 is aside elevation of my machine. Fig. 3 is an end elevation having aportion of the `outer casing'broken away to show the cir- `is adjustablysecured by threaded attach- Patented J an. 2, 1912.

ment at B. The threaded ring portion of the cap 2, is divided'at C, (seeFigs. 4 and 5) and may be clamped securely to the flange A, by means ofthe bolt 3, and the nut 4, thereby locking together parts 1, and 2, toform the outer rotative shell hereinafter alluded to, and referred to'inthe claims. Said outer shell Iis supported by, and is rotative inbearings 5, and 6. The head-end,

yor disk-like portion of cap-2, is connected to said threaded ringportion by the arms 7, between which the openings 8 are provided toallow the escape of the crushed product.

9v is a belt-wheel keyed to shaft 1, for applying power to rotate saidshell. Inside the hollow shaft l, is mounted the shaft 10, whichhas itsbowl-shaped end.D,'seated i by ball and socket joint 11, in fiange A.The outer end of shaft 10, is carried by the bearing 12, which issupported by and made laterally adjustable in the box-frame 13. Thelateral adjustment of bearing 12, is effected by means of screw-bolts14, which connect it with 13. The collar 15,- is secured to shaft 10, toprevent the longitudinal movement thereof. The opposing, circular,vcrushing plates 16, and 17, are removably secured respectively to theinterior surface of cap '2, and the bowl-shaped end'D of shaft 10. Thebolts. 18 and. the central screw 19 are employed to hold said crushingplates in position but any other means of attachment may be used as maybe-/best suited to the form of-said plates, either of which may be madein a single piece, as shown, or divided into parts constituting dies.The circular crushing plates 16, and 17, present opposing dished orconcave surfaces inclosing between them the crushing cavity 20,

into which thecentral feed opening 21 .nally adjustable in supports 24,and 25,

thereby allowing the hood 22, to be shifted to suit the 'differentadjustments of cap 2. Set-screws 27, are employed to lock shafts 23, inany determined position. The crossbar 2S, secured to the hood 22,supports the feed-spout 29.

It is to be noted that thel crushing plaie 17, secured to the enlargedend of shaft 10 is so mounted within the outer rotative shell j whichcarries plate 16, that the two crushing plates tend to rotate in unison,or concordantly, when power is applied to the beltwheel 9; and that thistendency of the two crushing plates to rotate together is due to thefrictional contact of the ball and socket surfaces in the bearing 11,and is further due, when the machine is in operation, to the connectionsformed between the two plates by stone or other material wedged betweenthem. It is' further obvious that when the axes of the two crushingplates are disposed at a' given angle to each other, the planes in whichsaid plates rotate are respectively disposed at a like and equal angle.By this respectively oblique disposition of said plates they are causedto approach nearer to each other at 30 than at 31; and, likewise, duringtheir rotation, two opposing halves of said plates are constantly movingin a zone of mutual approach, while two opposing halves are moving in azone of respective recession. This method of maintaining, duringoperation, areciprocating or crushing movement of said plates, wherebymaterial carried with said plates in their rot-ation is forced into adiminishing cavity, and so crushed, is the conception of primaryimportance in my invention.

When in -the operation of my machine, power is applied to rotate thecrushing members as described, stone, ore,'or other material may b evfed into the'spout 29, whence it falls within the crushing cavity untilcaught between the approaching rotating crushing plates and socrushed.At the same time said material' is borne forward by said members intheir rotation, whence it derives a centrifugal force which operates tocarry it outwardly between said plates during their opening or divergentmovement. That part of the material which has been suiiciently reducedin size to escape through the peripheral opening between said plates,flies outwardly and is caught bythe to the speed of my machine. Thisaifords an important advantage over other machines fed by the limitedforce of gravity which is often insufficient to force through wet orsticky material and'sojprevent clogging. Especially is clogging-likelyto occur in other machines when fine crushing is attempted both becauseno provision is made for spreading the material over a crushingsurfacewhich presents an increasing area as reduction progresses, andbecause no provision is made for shortening the crushing stroke to suitthe final reduction of small particles near the eXit of the crushingcavity. ln inymachine the crushing plates may be brought close togetherfor fine crushing by turning the cap 2, on its threaded support at B,when said cap 2, is locked in position by means described.

The crushing stroke, or reciprocating movement of the crushing members,may be shortened by turning the screw-bolts 14, to bring shaft 10, morenearly parallel to shaft 1. The angle between the respective planes ofthe rotative crushing members is thus reduced. These provisions foradjusting the relative position of the crushing plates, and forregulating their crushing movement to suit such adjustment incombination with the provision made for the stone to vspread from thecenter 'to the circumference of a circular crushing area while in theprocess of reduction, especially adapt my machine for performing thework of fine crushing; while by reversing the adjustments descril'wd acoarse product may be readily obtained. Ry the arrangement of the twoshafts with the ball and socket bearing an oil passage between them isprovided for.

It will be understood that my inventiony relates for the most part to aCrusher in which the shafts are mounted on a supporting frame insubstantially a horizontal position. When in such a position the meansfor preventing the relative longitudinal movement of the vtwo shafts isoperative and of great importance.v The particular means .which I haveshown are to be taken in a 25 I conditions which make-the feed bygravity carry the material outwardly andthe whole which mustbe soconstructed as to present a central cavity the two faces Of which areremoved more widely than the faces at the discharge portion, it tends ofcourse to wear the crushing surface. Hence thenecessity f of fasteningthe crishing disk surfaces so that their attaching portions are notsubject to such wear. This may be done as illustrated by attaching onewearing surface at the center or Opposite the feed opening and byattaching the other from the back so that the attaching devices lieentirely away from the effective crushing surfaces themselves. Some ofthe features of my invention are Of course applicable to amachine in avertical position. When the shafts are in a vhorizontal position the endthrust due to the weight of the inner shaft is avoided the feed isdirected toward the center under operation of spouting the material intothe machine -and taking it from `it is greatly facilitated.

Having thus described my invention what I claim as new and desire tosecure by Letters Patentl is:
